These RoHS-compliant revolving ball knobs can be utilized instead of other revolving handles, i.e. with handwheels. The tapped shoulder allows the ball knob to be mounted from the underside via a screw or bolt. The knob can then be easily mounted to sheet metal in a variety of thicknesses, flat bar, or castings, to create a quick cranking or turning mechanism.
The hand piece is black phenolic plastic (Duroplast PF), and the shoulder is made of zinc-plated, blue passivated steel, blind tapped.
